HINGE.

Application filed Deceznber 6, 1921. Serial No. 520,408.

To all whom it may concern:

Be it known that I, DENNIS MoNnILL, a citizen of the United States, anda resident of Huntington, in the county of Cabell and State of WestVirginia, have invented a new and Improved Hinge, of which the following is a full, clear, and exact description.

This invention relates to improvements in hinges, an object of theinvention being to provide an improved construction of hinge pin havinga longitudinal lubricant .containing groove therein which serves tolubri cate all movable parts of the hinge and can be readily removed,cleaned and refilled from time to time as may be desired. l

A further object is to provide a hinge having an improvedconstruction'of hinge pin which can be manufactured and sold at a costthe same as the ordinary hinge pin as it can be formed in the die inlike manner with the ordinary structure, and yet which will providemeans whereby a lubricant can be maintained in proper relation to themovable sleeves or elements in the hinge to lengthen the life of thehinge and prevent noise by operation thereof.

With these and other objects in view the invention consists in certainnovel features of construction, and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings Figure 1 is a view mainly in front elevation, but showing in longitudinal section the hinge knuckles and thehinge pin in elevation thereon.

Figure 2 is a view in section on the line 2-2 of Figure 1. p

1 and 2 represents the leaves of an ordinary separable hinge and 3 isthe aligned sleeves or hinge knuckles which receive my improved hingepin 4:. This hinge pin 4 is removable as is customary, and is providedpreferably with a knob 5 at one end corresponding with the fixed knob 6on one of the leaves of the hinge.

It is, of course, obvious that the exact shape of the pin head or otherform of head is immaterial, but it is, of course, necessary to have someform of head to limit the movementof the moval. a p

My improved hinge pin is made with a longitudinal groove 7 extendingthroughout its length, or at least throughout that portion of its lengthwhich acts as a pintle within the sleeves or knuckles 3 of the hinge.This groove 7 is filled with a lubricating composition 8 which is ofsufficient consistency to remain in the groove and. yet lubricate thesurfaces and supply lubricant for an indefinite length of time. Theinvention is, of course, not limited to the "particular lubricatingmeans employed in the groove as it is obvious that this is subject tomodification, but my invention resides in the propin and to facilitateits revision of a longitudinal groove in a hinge. pln adapted to containlubricating means which supplies the surfaces adjacent thereto.

I am, of course, aware that lubricating grooves in various articles areold, but the provislon of a lubricant containing longitudinal groove ina huge pin is an absolutely new idea so far as I have any knowledge andin the provision ofv such a construction of pin lam enabled to use thesame as any ordinary pin or replace ordinary pins and provide alubricant containing pin which supplies the lubricant as it is needed,and, furthermore, can produce such a lubricating hinge pin that its costis no greater than v the cost of the ordinary pin.

Various slight changes might be made in the general form and arrangementof the parts described without departing from the invention, and hence Ido not limit myself to theprecise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claim.

I claim: I e

As a new article of manufacture, a hinge pin, a head on the hingepin,and said pin having in its outer face and throughout its length astraight longitudinal lubricant, receiving groove, said head operatingas a closure for the upper end of the groove when the pin is in positionin a hinge.
